You'd think MI6 agents would handle top-secret data more carefully than on memory stick in a purse, right? Well that purse was left behind on a train in 2006, compromising a multi-million dollar drug operation.

Secure Computing says that an agent only known as T was responsible for the gaffe, which took place on a Colombian passenger train. Apparently the fallout from the incident resulted in a number of agents having to be relocated for safety purposes. But MI6 assures us all that they now take more secure precautions with sensitive data. [Secure Computing via Wired]
